2026 Complete Guide for Import Agency of New Plastic Raw Materials - Full Process Analysis of Customs Clearance, Price Assessment and Inspection

Last month,we met Ms.Xue from Suzhou,who imported 5 containers of new ABS plastic raw materials from South Korea.When she filed the declaration through a customs broker she found herself,she classified the HS code as 39033090,which resulted in a 12% higher Most Favored Nation (MFN) tariff than the correct code.She paid over 70,000 yuan extra in duties alone,and later spent 21 days applying for an amendment,incurring nearly 20,000 yuan in terminal detention fees.Such issues are very common in new plastic raw material import business and can be completely avoided with advance compliance checks.

Core Compliance Points for Import of New Plastic Raw Materials

• Accurate HS Code Classification In 2026,customs updated 3 classification subheadings for plastic raw materials,adjusting classification thresholds for common types such as PP,ABS,and PC.12 declaration elements including monomer content,melt flow index,tensile strength,and modification status need to be verified.Incorrect classification may lead to duty supplementation and document deletion at best,or trigger anti-smuggling inspections at worst.We have an 18-year accumulated database for plastic raw material classification,with a classification accuracy rate of 99.8%.
• Pre-Inspection of Documents Required documents include MSDS (non-hazardous certificate),original invoice,packing list,bill of lading,and certificate of origin.According to the new RCEP certificate of origin regulations in 2026,the issue date must be within 7 days after shipment; otherwise,the tariff reduction ranging from 0% to 8% cannot be applied.We will complete verification of all documents 3 days before shipment,and revise non-compliant documents in advance to avoid delays upon arrival.
• Advance Anti-Dumping Duty Screening In 2026,China still imposes anti-dumping duties on some PVC,PS,and EPS plastic raw materials originating from the EU,South Korea,and Taiwan,China,with tax rates ranging from 2.3% to 47.8%.If the country of origin is on the tax list,costs can be reduced through compliant transshipment planning and origin qualification verification,avoiding wrongful payment of high anti-dumping duties.

Practical Case of New Plastic Raw Material Import Agency

Last year,Manager Xiang from Dongguan approached us.He previously imported 12 containers of new PC plastic raw materials from Thailand.When he handled customs clearance on his own,he failed to enjoy the 8% RCEP tariff reduction because the certificate of origin was issued 3 days past the deadline,resulting in a loss of over 120,000 yuan.His requirements this time were clear: first,to legally enjoy tariff reduction; second,to deliver the goods to his Dongguan factory within 3 days after arrival.

We received all documents 7 days in advance for pre-inspection.First,we verified the declaration elements corresponding to the HS code: melt flow index 12g/10min,light transmittance 92%,no additives,all parameters fully matched the physical inspection report.Then we checked the issue date,seal,and origin standards of the certificate of origin,confirming it met the RCEP tariff reduction requirements.Meanwhile,we completed pre-inspection for commodity inspection and filed the pre-declaration 24 hours before the vessel arrived at Shanghai Port.Finally,the goods were released on the day of arrival,and we secured the 8% tariff reduction,saving a total of 136,000 yuan.It only took 2 and a half days from arrival to delivery to the factory,fully meeting Manager Xiang’s requirements.

Risk Warning for Import of New Plastic Raw Materials

• False Declaration Risk In 2026,customs upgraded the inspection model for plastic raw materials.If the deviation between declared elements and physical inspection results exceeds 5%,the case will be transferred to anti-smuggling authorities,resulting in a fine of up to 5% of the cargo value at best,or suspension of the enterprise’s import and export rights at worst.We arrange dedicated personnel to verify each declared item against the physical goods to ensure consistency between documents and cargo.
• Exchange Loss Risk In 2026,the two-way fluctuation range of the RMB exchange rate increases.If settling in US dollars,a payment cycle exceeding 15 days may lead to 1%-3% exchange loss.We can assist enterprises in connecting with compliant financial institutions for exchange rate locking operations to fix payment costs and avoid extra losses caused by exchange rate fluctuations.
• Title Risk When importing plastic raw materials from Europe,America,and the Middle East,if local holidays such as Christmas or Ramadan are encountered,port operation efficiency drops by over 30%,which may lead to delivery without a bill of lading.Our global cooperation network covers more than 120 countries and regions,allowing us to connect with local freight forwarders in advance and monitor the title status throughout the process to avoid loss of both money and goods.
